The flexibility of the JDBC API also permits you to create a cursor that you can use programmatically to perform positioned updates and deletes by issuing the appropriate SQL commands.

JDBC API 的灵活性还允许您创建一个可以通过编程的方法来使用的游标，用于通过发出相应的 SQL 命令执行定位更新和删除。

youdao

The next step is to create the named cursor, which you do by using the GET cursor command along with the necessary SQL query that selects the rows for the cursor.

下一步是创建指定的游标，方法为使用GET CURSOR命令，以及使用必要的SQL查询为游标选择行。

youdao

Here you use the get cursor command to create a cursor, feeding it an SQL statement that represents the data you want to include.

在此处您可以使用get cursor命令创建一个游标，并馈送它一个sql语句，表示您要包含的数据。
